The pit is fashioned according to the needs of the beneficiary. A family harvesting water will need a small-sized pit, whereas a farm will require a set of about ten deeper systems. However, the design of each pit is relatively the same.
How the Syringe System Works:
• For an average-sized system, one needs to dig a six-metre pit into the ground and fill it with river sand for up to three metres.
• This sand acts as a filter through which the water seeps and accumulates below the land surface.
• Above this, lies the catchment area constructed with concrete. Water is not collected in a tank but below the ground.
• A foot valve installed at the bottom of this pit is connected to a motor that draws water for use.
• The system essentially aims at increasing the groundwater levels.
Our concrete or tar roads keep rainwater from percolating in the earth’s surface to swell the underground water table. Secondly, the lack of plants or trees leads to soil erosion. But Antoji utilised the very pressure that erodes the soil, harming the environment and ensured that the water seeps through.
The Rainwater Syringe System has its own method to direct the water deep below the earth’s surface. The fresh rainwater in the shallow tank can hold up to a 1,000 litres of water. When it fills up, the total pressure pushes the water below. This pressure is so powerful, it can make the water percolate to about 70 feet deep. A specially made motor pump is used to pull this water from that depth. The motor draws the water from below the earth’s surface to the overhead tank whenever you need to use it,” he further explains.
One of the beneficiaries of Antoji’s Syringe System is a resort in Andaman. The resort, severely hit by a shortage of potable water, had to close shop for three months. Andaman and Nicobar, much like Kerala, faces the same problem of the mixing of saline with fresh water.
The resort was an obvious victim.
Coming to its rescue, Antoji’s Syringe System is now helping the resort receive about 1,500 litres of water daily.
“We have installed a system of 10 units—each 10 feet deep—in a 5-acre agriculture land in Kerala,” he shares and adds that the farmer utilises the collected water to farm for the year. Rainwater syringes have proven their success over the last three decades, but they are the most efficient only at sea levels. So places like Kerala, Andaman and Gujarat benefit from them.”
Since its finalisation, Antoji’s invention has been installed in about 400 places, including private homes, farms and resorts. With a 90 per cent success rate, the Syringes have restored over 300 crore litres of water into Kerala’s ground.
Antoji’s journey was not without challenges as due to his limited knowledge about patents, he suffered at the hands of the local government, whose water supply he had cut out completely. The irony is that he had only wished to help them with his innovation. Undeterred by the legal and authoritative nuisance he had to face, Antoji still oversees the installation process, whether in Kerala, Andaman, Gujarat or anywhere else in the country.
